Hi, i make this video for calibration of the wide angle on the iphone 13. i made one in 4k and one in 1080p, does it make a difference? would really appreciate a calibration file for this. also, does anyone know how to do the calibration? would be a lot easier to take the load off of you. thanks!

This is the calibration data for the 4k mode. Save it as a json file. When picking the camera model, click the ‘Load from file’ button and select the saved json file.

Which camera (main or ultra wide) was this video taken by? Was the zoom set to x1?
Also, I didn’t do the calibration for the 1080p mode. There is no point to shoot 1080p videos when the stitched resolution will be less than 4K.
Hi, yeah both were recorded using the 0.5x camera angle. Also, Ide love to 1080p version cause it’s saves so much space on the phone when you record longer matches and I don’t have enough for 4k 1 hour footage
also could you let me know how the calibration process works so i can do it myself? Thanks!
i get this error when using the .mov file that come out of the iphones, even with both at the same settings, and if i change them to MP4 i still get that error. i have to put them into imovie and export them again for it to accept them, but when i do that, i use the calibration profile you provided but then every time i get a different broken visual for the stitching like below:
or an even more distorted every time i slick stitch, it comes out slightly different. im using the same settings i did the calibration with
what to do?
